At least one constructional element made of heat-storing material is thermo-conductively connected to at least one cooling element exposed to cooling water. The surface of the cooling element is heat-conductively connected to a surface of the first building element. A second building element of heat-storing material is parallel with, and spaced apart from, the surface of the first building element so as to leave a vertical convector shaft with at least one top and one bottom air passage.
